Website data capture: website data collection proxy IP program

Why do I have to use a proxy IP to capture website data?

The biggest headache of data capture is to be the target site blocked IP. a chestnut, if you use your own broadband connected to catch the price of an e-commerce site, within half an hour will give you a blacklist. At this time, the proxy IP is like a reptile wearing a vest, each visit to change the identity of the site can not distinguish between a real person or a machine.

Here's the kicker.IP Rotation Mechanism. Suppose you want to grab 1000 pages, if you only use 1 IP, it's equivalent to letting the website security remember the same person's face. But if you use ipipgo's proxy pool and change a new IP for each request, it's equivalent to having 1000 different people knocking on your door for you, and the probability of being caught plummeting.

What are the doors to look for when choosing a proxy IP?

There are all sorts of agency services on the market, so here are three tips to avoid the pitfalls:

As a special reminder, some agents will playshared IPThe first thing you need to do is to get a good deal of money. It's like sharing a house, dozens of people share an IP, with this kind of IP to engage in the collection of absolutely overturned. ipipgo's exclusive IP package is expensive, but the stability of double, especially suitable for the need to run the project for a long time.

Practical Proxy IP Configuration Guide

Here's a Python sample code for automatic IP replacement using the requests library:

import requests
from itertools import cycle

 List of proxies from the ipipgo backend
proxies = [
    "http://user:pass@gateway.ipipgo.com:9020",
    "http://user:pass@gateway.ipipgo.com:9021".
     ... More Proxy Nodes
]

proxy_pool = cycle(proxies)

for page in range(1, 101):
    current_proxy = next(proxy_pool)
    try: current_proxy = next(proxy_pool)
        response = requests.get(
            f "https://target-site.com/page/{page}",
            proxies={"http": current_proxy}, timeout=10
            timeout=10
        )
        print(f "Successfully crawled page {page}")
    except.
        print(f "Failed with {current_proxy}, automatically switch to the next one")

Here's the kicker.timeout settingThe proxy pool should be updated every half an hour. It is recommended to set it within 10 seconds, and switch proxy IPs in time when you encounter a lagging one. ipipgo's API supports getting the list of available IPs in real time, and it is recommended to update the proxy pool every half an hour.

Frequently Asked Questions QA for beginners

Q：Why was I blocked even though I used a proxy?
A: 80% of the use of low-quality proxy IP, check whether the use of transparent proxy, or IP reuse too many times. We suggest you to use ipipgo's high-storage proxy package, their IP survival time is controlled within 30 minutes.

Q: What should I do if I can't connect to the proxy IP often?
A: This happens mostly with free proxies. You can try ipipgo'sIntelligent RoutingThe system will automatically select the node with the lowest latency. If you are doing overseas collection, remember to choose the IP pool of the corresponding region.

Q: How do I choose a package for my enterprise level project?
A: Directly look for ipipgo customer service to ask for a customized plan. They have a specialized technical support team that can match different ratios of residential IPs and server room IPs according to the frequency of your collection and the strength of your target site's anti-climbing.

Say something from the heart.

Doing data collection in this line, the proxy IP is the guy who eats. In the early years, I also figure cheap with a free proxy, the results of the project ran half of the IP hung, the party almost sued me. Later turned to use ipipgo monthly package, although more than a few hundred dollars a month, but then there is no large-scale IP blocking.

Finally, remind newbies not to save money on proxy IPs. Instead of spending time tossing free proxies, save time optimizing the collection logic with a reliable service.
